Drop, Cover, and Hold On

Daisy loves the pastries in Harris' bakery, the only problem is Harris seems to hate Daisy, and they end up stuck there together on Valentine's Day. I still can't understand how Harris can not only hide his feelings but project the exact opposite at every interaction for months. It does not seem he lacks people skills, he's nice to other people! And they go from 0-100 at lightning speed. Not convinced.
